What Causes the Trunk Door Latch to Make Noise?

The reason for the trunk door latch making noise: It may be due to cold weather causing the rubber seal to stick together. Other reasons: Frequently using the key to open the trunk can cause the linkage rod to disconnect, requiring a visit to the repair shop. If the trunk is always opened with the remote, the lock cylinder may be dirty or rusty. Spraying rust remover into the lock cylinder a few times can help open it. Mechanical component failure: The trunk wiring may be broken, or other trunk-related issues may prevent the car trunk from opening. It is recommended to visit a 4S shop for repair or replacement. Additionally, if the trunk wiring is broken or other trunk issues prevent the trunk from opening, the problem may be with the linkage rod or lock cylinder.

I've encountered the issue of a rattling trunk latch several times. It's mainly caused by loose parts, like the spring or screws, which can shift and produce squeaking sounds after prolonged driving and bumpy roads. Sometimes, it's due to dust accumulation or rust, and in hot summers, metal expansion can also cause noise. I've found that if the screws are loose, tightening them with a wrench when parked can help, and spraying some lubricant can immediately silence the noise. Ignoring it may lead to a broken latch over time, making it difficult to close the trunk and posing safety risks. During regular maintenance, have someone check it to prevent small issues from becoming big problems. My advice is not to overlook these details—ensuring your car's safety brings peace of mind.

The trunk latch on my car keeps making a rattling noise, like a clicking sound. I think it's because we open and close it too frequently, and the spring might be worn out or the latch deformed. It gets especially loud when driving on bumpy roads. My wife says it's super annoying. I usually just stuff an old rag next to the latch or spray some machine oil as a quick fix, which basically solves the problem. Remember not to overload the trunk with heavy items, as the extra weight on the latch will make it worse. Older cars are more prone to this issue. Just ask the mechanic to adjust it during annual maintenance—it's a small expense. Anyway, this is a common problem that's not hard to deal with, but if you delay fixing it, you might end up needing to replace parts, which would be a waste of money.

Bro, my car's trunk latch also made noise, especially creaking on rough roads. The reason is heavy vibrations plus temperature changes causing metal parts to loosen or deform. I bought some spacers on Taobao and stuck them on, which worked okay. Don't just endure it—check if the screws are tight and spray some lubricant. If left untreated long-term, the latch might break, making driving stressful. New car owners should pay attention—this minor issue isn't hard to fix.
